Colour conversion on the iPhone 4S - Recommended

My current iPhone 4S screen is damaged and I was thinking of changing the colour whilst I had the opportunity. I do like the mirrored deep blue as seen on the youtube video below. Has anyone got any advice etc before I part with my cash?

If you do go with a higher quality one. I went with one in a local store, did the retro fit myself and was not happy.
They tinted the entire front part, including the glass over the LCD, so my screen always had a bluish tint. The first time i looked at it outside was a joke. The reflective blue blinded me. LOL Also my reception with it sucked. I blame that on the crappy battery door.
